U-M researcher and colleagues predict large 2009 Gulf of Mexico 'dead zone'; Chesapeake Bay's oxygen-starved zone likely to shrink
University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year's Gulf of Mexico "dead zone" could be one of the largest on record, continuing a decades-long trend that threatens the health of a half-billion-dollar fishery. view more (2009-06-19)
Oxford spin-out company may lead to treatments for a range of diseases
Oxford University's latest spin-out company, ReOx, is set to develop potential therapies for a huge range of diseases, from heart disease to stroke, using world-leading expertise in biology and chemistry. The company was spun out this summer and has raised £2 million in capital investment. ReOx is a drug discovery company whose technology... view more... (2003-07-17)
Adaptive functional evolution of leptin in cold-adaptive pika family
Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal. view more (2008-01-23)
Experimental treatment halts hypoxic-ischemic brain injury in newborns
Inhibiting an enzyme in the brains of newborns suffering from oxygen and blood flow deprivation stops a type of brain damage that is a leading cause of cerebral palsy, mental retardation and death, according to researchers at Cincinnati Children's Hospital Medical Center. view more (2009-07-29)
Older men with breathing problems during sleep more likely to have irregular heartbeats
Increasingly severe sleep-related breathing disorders in older men appear to be associated with a greater risk of abnormal heart rhythms (arrhythmias). view more (2009-06-23)
Protein regulates movement of mitochondria in brain cells
Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease. view more (2009-06-15)
Oxford Biomedica and the Institute of Opthalmology present preclinical results from the RetinoStat programme for vision-loss
Oxford BioMedica and The Institute of Ophthalmology are describing two key features of the Company's vision-loss product RetinoStat(TM) at The Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO), held in Fort Lauderdale, Florida, during May 4th-8th. This is the world's biggest forum for eye research and is attended by... view more... (2003-05-06)
Brown Scientist Finds Coastal Dead Zones May Benefit Some Species
Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted waters. view more (2008-10-15)
How vitamin C stops the big 'C'
Nearly 30 years after Nobel laureate Linus Pauling famously and controversially suggested that vitamin C supplements can prevent cancer, a team of Johns Hopkins scientists have shown that in mice at least, vitamin C - and potentially other antioxidants - can indeed inhibit the growth of some tumors - just not in the manner suggested by years of... view more...

Erectile dysfunction related to sleep apnea may persist, but is treatable
For sufferers of sleep apnea, erectile dysfunction (ED) is often part of the package. New research indicates that ED in cases of obstructive sleep apnea syndrome (OSAS) may be linked to the chronic intermittent hypoxia-oxygen deprivation- (CIH) that patients with OSAS experience during episodes of obstructed breathing. view more (2008-09-12)
Severe COPD may lead to cognitive impairment
Severe chronic obstructive pulmonary disease (COPD) is associated with lower cognitive function in older adults, according to research from Mount Sinai School of Medicine. view more (2009-07-08)
Botox could help target resistant tumors for treatment
The cosmetic treatment Botox may have a new use as an adjuvant to cancer therapy, providing an open door for chemotherapy and radiation treatments. view more (2006-02-15)
Anesthesia and Alzheimer's
In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein. view more (2008-04-28)
PLoS Biology Press Release: Hypoxia Offsets Damage from Oxygen Therapy, Real Time Microscopy Tracks Developing T Cells, and More
Hypoxia Can Offset the Potentially Damaging Effects of Oxygen Therapy Physicians well know that too little oxygen (hypoxia) causes headaches, nausea, and eventually death. But too much oxygen (hyperoxia) kills, too. In a new study in the open-access journal PLoS Biology, a team led by Michail Sitkovsky show that oxygenation weakens a... view more... (2005-04-27)
Elevated nitric oxide in blood is key to high altitude function for Tibetans
How can some people live at high altitudes and thrive while others struggle to obtain enough oxygen to function? view more (2007-10-31)
Pitt professor says harmful byproducts of fossil fuels could be higher in urban areas
Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize. view more (2007-10-23)
Stanford study prevents pancreatic tumor growth in mice by inhibiting key protein

Premature infants, toddlers more likely to have a sleep-related breathing disorder
A sleep-related breathing disorder among infants and toddlers born prematurely occurs earlier than expected in this population, and at higher rates than among full-term infants. view more (2007-06-11)
Smoking during pregnancy a 'double-edged sword' in SIDS
Premature infants whose mothers smoked during pregnancy may be at even higher risk for sudden infant death syndrome (SIDS) than preemies whose mothers did not smoke, according to new research out of the University of Calgary. view more (2008-08-29)
University of Kent bioscientists receive grant to research novel cancer treatment
Dr Phil Blower and Dr Dan Lloyd from the Department of Biosciences at the University of Kent - together with Dr Paul Marsden at the St Thomas' Hospital Clinical PET Centre in London - have been awarded £347,906 from the Engineering and Physical Sciences Research Council and the Medical Research Council for a project entitled Radiocopper... view more...
